Simulation of the Cracking Behavior for Fiber Reinforced Composite Materials with the Infulence of Depth-Width Ratio and Direction Angle

Abstract:

Based on the Voronoi cell finite element can also reflect fiber reinforced composites interface to take off the layer and matrix crack propagation of the new cell (X-VCFEM cell)[1]. Combined with the re-mesh strategy and grid dynamic technology, Simulated analysis in different angles and different depth-width ratio, interface crack propagation for fiber reinforced composites, the results show that when 0˚< < 90˚, the horizontal tension increases with the increasing; When 90˚< < 180˚, the horizontal tension decreases with the increasing; And when =90˚, the horizontal tension was the largest; the horizontal tension increases with the depth-width ratio increasing. The result was very important reference value for manufacturing process and engineering application of fiber reinforced composite materials.
